Have you ever thought about training seals? If so, what about penguins? there is a book just about it and it's called Mr.Popper's Penguins.
It's about a person called Mr.Popper and he gets a penguin from a person on an expedition to the South Pole that is called Admiral Drake. I can't tell you the rest of the information, you have to find the rest on your own.
By the way, penguins do not live in the north pole
